Definitions
- the present invention relates to a method for producing a particle-based element, in particular a chipboard, or fiberboard.
- a method for producing a particle-based element is known, for example, from international patent application WO 2009/017451 A1, which discloses a method for producing a wood-based furniture component.
- wood chips are pressed so that a plate-shaped component is formed with projections, which is combined with another component such that there are voids between the projections.
- a lower consumption of wood chips in the production and a lower weight of the component can be achieved.
- the stability and possible areas for possible attachment of structural connections of the component through the cavities are reduced.
- DE 10 2004 024 878 A1 discloses a sandwich element which is formed from two outer layers and a middle layer arranged therebetween, wherein the central layer can be designed in the form of a periodically recurring, double-curved shell structure. Furthermore, it is disclosed that the spaces between the cover layer and the central layer can be completely filled on one or both sides with a suitable material, for example with a foamed material, in order to achieve an insulating effect.
- a suitable material for example with a foamed material
- the object of the present invention is to provide a method for producing a particle-based element, which on the one hand can be operated inexpensively and quickly and, on the other hand, enables the production of particle-based elements with tailor-made structural properties.
- a first three-dimensionally shaped structural element having first particles is produced.
- a second structural member having second particles is formed complementarily and the first and second structural members are joined.
- Complementary forms means in In this connection, that the surface structure of the first structural element forms a positive shape, which is precisely to a surface structure of the second structural element and thus forms the corresponding negative mold.
- the complementary shaping of the second structural element and the joining of the first structural element to the second structural element can take place either successively or simultaneously. Due to the three-dimensionally shaped structure of the first structural element and the complementary shaping and bonding of the second structural element thereto, an integral element with improved structural properties can be achieved. In particular, an increase in the structural stability can be achieved with at the same time low weight of the particle-based element.
- one of the structural elements is shaped so that it has a higher stability than the other structural element, which has a lower density for it.
- the particle-based element has a plate shape formed in the longitudinal and width directions.
- the inventive arrangement can also achieve a particle-based element with increased flexibility, in which areas of lower stability and / or density are deliberately arranged within the particle-based element.
- the first structural element and / or the second structural element is produced by applying heat and / or pressure to a particle mass. Due to the heat or the pressure, the particles of the structural elements which form the particle mass can be connected to one another. Furthermore, a compression of the particle mass can be achieved by the pressure, whereby a structural element can be produced, the density and strength are determined largely by the pressure during manufacture.
- the first structural element and / or the second structural element is produced by introducing a chemical agent into a particle mass.
- the chemical agent may be an adhesive and / or hardener which cures the particle mass to one another by bonding the particles together, but also by solidifying the individual particles.
- both the application of heat and / or pressure or the introduction of chemical agents can only take place locally in the first or second structural element, so that locally different densities or stability of the structural element can be achieved. This can be targeted areas with higher stability or lower density can be generated.
- one of the structural elements has a higher density and / or stability than the other structural element.
- one structural element in the particle-based element forms a region of higher stability or density, while the other structural element forms a region of lower density.
- a particle-based element can be made, which achieves a high structural stability by the structural element with higher density and / or stability, wherein the particle-based element nevertheless has only a low weight.
- the complementary shaping of the second structural element and the joining of the structural elements can be carried out in one step.
- a work step can be saved and, on the other hand, an optimum adaptation of the shapes of the complementary joining surfaces between the structural elements can be achieved.
- the second structural element is formed as a matrix for the first structural element.
- the first structural element is received in a structure formed by the second structural element.
- the first structural element does not necessarily have to be formed continuously, but may also be formed by a plurality of individual locally arranged elements.
- the second structural element thus forms a continuous structure in which the first structural element is arranged.
- the second structural element can also be formed within a matrix formed by the first structural element.
- the first structural element now forms the continuous structure.
- the second structural element may in turn consist of a plurality of local non-connected elements.
- one of the structural elements is configured to extend from a top side region to a bottom side region of the particle-based element.
- One of the structural elements may be formed by suitable extension in the vertical direction of the plate formed in the width and the longitudinal direction, at a distance from the neutral zone or plane, and continuously, so that the mechanical properties can be improved.
- one of the structural elements is formed so that it extends in a wave-shaped manner in a longitudinal direction of the particle-based element.
- the wavy shape of the structural element allows the structural stability of the particle-based element to be increased by the reinforced areas arranged outside the neutral zone.
- the waveform provides stability benefits because there are no angular bends that can adversely affect structural element stability.
- the undulating structural member is of higher stability than the other structural member. In addition, this significantly increases the shear strength of such an element.
- the one of the structural elements is formed so that it also extends in a wave direction in a width direction of the parttkelbas elected element.
- a particle-based member having increased flexural rigidity both in the width direction and in the longitudinal direction can be formed.
- the first structural element is preformed inserted into the second particle before the second structural element is formed by a pressing operation.
- the structural elements may be made with a different density in the region of their surface, as compared to the density in the interior of the structural elements.
- a compaction in the surface area of the particle-shaped structural elements can be achieved in a variety of manufacturing processes, for example by a pressing process, but also by suitable treatment of the top and bottom regions of the particle mass of the structural elements.
- a region of increased stability is formed to extend from a top side region to a bottom side region of the particle-based element.
- the region of increased stability is formed in particular by the first or the second structural element and makes it possible to increase the stability of the particle-based element, in particular if it has a plate shape in the width direction and the longitudinal direction and the region of increased stability extends in the vertical direction.
- the region of increased stability is designed such that it extends in a wave-shaped manner in a longitudinal direction of the particle-based element. This makes it possible to increase the flexural rigidity, especially in the width direction of the particle-based element.
- the region of increased stability also extends in a wave direction in a width direction of the particle-based element.
- an increase in the stability both in the width direction and in the longitudinal direction of the particle-based member can be enabled.
